Ether 14:28

And they pitched their tents in the valley of Corihor; and Coriantumr pitched his tents in the valley of Shurr. Now the valley of Shurr was near the hill Comron; wherefore, Coriantumr did gather his armies together upon the hill Comron, and did sound a trumpet unto the armies of Shiz to invite them forth to battle.
